[engage: lengthy critique]
LEGS: Shins are good, and thighs look okay in the first pic. But seeing their construction from the side... looks like it falls into the category of trying to make them custom without really needing to, and the legs suffer as a result. The placement of the wing pieces doesn't help much either.
FEET: Good on you for making custom feet, not a lot of people do that. You might want to move the sockets around ninety degrees so that you have more articulation in the front and back.
TORSO: Eh no. Definitely looks very spindly, even for a female. My suggestion is to loose a bit of height on the torso - such that the hands reach down to the mid-thighs, which is proper human proportions - by whatever means you have. Once that is done you should be able to keep the width you have as is.
ARMS: They're alright, as much as prefab limbs can be.
WEAPON: Really the critique here boils down to whether you want it to look like she's wielding a realistic crossbow thingy or an exaggeratedly cartoonish one.
